Given numbers are 555, 777, 305, 209

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(555, 777) = 3885

GCD(555, 777) = ( 555 x 777 ) / 3885

= 555 / 777

= 555

Step2:

LCM(111, 305) = 33855

GCD(111, 305) = ( 111 x 305 ) / 33855

= 111 / 305

= 111

Step3:

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

= 1 / 209

= 1

So, Greatest Common Divisor of 555, 777, 305, 209 is 1
